Triterpenoid α-amyrin stimulates proliferation of human keratinocytes but does not protect them against UVB damage.
Summary of "Triterpenoid α-amyrin stimulates proliferation of human keratinocytes but does not protect them against UVB damage."
Rhaponticum carthamoides plants ("maral root") are widely used in Siberian folk medicine. The present study reports for the first time the presence of pentacyclic terpenoid, α-amyrin, in methanol extract from leaves of this plant. α-Amyrin induced proliferation of human keratinocytes (HaCaT) by about 18% while other extract components were ineffective. A panel of biochemical and cell-based assays testing the antioxidative and cytoprotective activites of α-amyrin indicated no antioxidative activity of this compound. α-Amyrin did not protect HaCaT cells against the damage caused by UVB radiation.

Cytokine that stimulates the proliferation of T-LYMPHOCYTES and shares biological activities with IL-2. IL-15 also can induce proliferation and differentiation of B-LYMPHOCYTES.
A humoral factor that stimulates the production of thrombocytes (BLOOD PLATELETS). Thrombopoietin stimulates the proliferation of bone marrow MEGAKARYOCYTES and their release of blood platelets. The process is called THROMBOPOIESIS.
May protect against hypoxic damage; proposed for treatment of shock due to trauma or blood loss; also stimulates paretic gastrointestinal system.
